The all natural alternative to activated carbon designed to buffer pH and last for months!

DVH Aquatics AquaChar

Most activated carbon in aquariums today use fossil fuel byproducts and hydrochloric acid. For millions of years forest fires and rain running into the streams, rivers and oceans has been nature´s way of cleaning itself. AquaChar is an all natural product. By burning wood at several thousand degrees hotter than the ash point of carbon, AquaChar leaves the lightweight carbon skeleton that trees use to grow intact. AquaChar is negatively charged. Broken down organics (which are positively charged) are the cause of most water clarity issues . AquaChar’s negatively charged ions pull fine particulates out of the water creating crystal clear water. AquaChar has natural porosity and a massive surface area (>20 bioballs per gram*) which makes it the ideal support system for beneficial bacteria to colonize.

DVH Ocean Prime Liquid

Reefs are an oasis of organism diversity, activity, color and beauty. The closer you view a reef, the more you experience the one common feed that supports the dynamic of the world's marine food web is plankton. Unfortunately, nutrient-rich zooplankton is missing from marine aquariums. Therefore aquarists provide the missing link by using Ocean Prima Liquid to achieve the beauty and diversity of a marine reef in their marine aquarium.

Copepods are a type of tiny crustacean zooplankton that is considered as the world’s largest bio-resource. Most aquatic species are dependent of copepods during parts of or their whole life cycle. They are eaten by fishes, larval fishes, corals, jellyfish, shrimps, filter feeders and many more.


Ocean Prime Copepods Liquid have a nutritional profile that meets the requirements of fish, crustaceans, invertebrates and corals. The typical lipid content is 10-15%, and a protein content of about 50% of dry weight. The lipids are rich in essential fatty acids as DHA and EPA bound to phospholipids and also contain high levels of pigments like astaxanthin. 

Ocean Prime Copepods are harvested in clean, unpolluted Arctic waters, with eco-friendly harvesting methods. The preservation technique.... Click here for more info

BioPellets The Original

We provide, as first in the world, a novel filtermedia entitled NP-reducing BioPellets to the professional aquarium industry including public aquaria, zoos and aquaculture facilities. This product has been developed for (professional) aquarists who want to supply their aquarium inhabitants with large quantities of feeds without negatively affecting water quality. The husbandry of marine species which require large amounts of nutrition has made a crucial step forward with this new product. Examples of such species are Anthias fish, soft corals such as Dendronephthya sp. and filter feeders such as sea squirts. Click here for more info 


All-in-One Advanced BioPellets

We were the first to develop and present the NP reducing Biopellets which are mostly removing Nitrogen waste products and to a small extend also Phosphates. Now it is time to take the next step, the DVH Aquatic All-in-One Advanced Biopellets. We listened to our customers feedback, the issues they encountered, and developed this new and unique Biopellet from scratch, in-house. The main challenges are still the nitrate levels and nowadays we know that phosphates are also a key factor for successfully keeping corals. Phosphate levels are relativity easy to lower in the water so we put our focus on even removing more nitrates with a minimal impact on the phosphates levels. Click here for more info

Coral Protec, Coral Dip 

Coral Protec is a great substitute for reefers who doesn’t have a quarantine tank setup. It is a quick and easy method for expelling all sorts of aquarium pests before you place your precious coral(s) into your aquarium. This simple process is a commonly looked over step in the acclimation process that can often leads to huge problems.
Prevention is the keyword here. Once a pest has managed to get in your aquarium, it’s very difficult to eradicate them totally. Coral Protec is effective in expelling the following parasites: Acropora Eating Flatworms (AEFW), Montipora Eating Nudibranchs, Zoanthid Eating Spiders, Red Flatworms and performs very well in the treatment of Rapid Tissue Necrosis (RTN), Slow Tissue Necrosis (STN) and Bacterial Infection.

Fragsation, The easiest way to fixate LPS and SPS frags

Fragsation is a reef safe, medical grade, polymer which melts at 61°C and consists of small off-white plastic granules. By heating these granules in hot water, the pellets form a transparent flexible material.

Once melted the white pellets become transparent and soften, allowing the user to fixate their LPS / SPS coral frags for example on a  frag plug, frag stone or live rock.

Fragsation is completely re-usable, allowing it to become flexible again once heated above 61°C. Available in 100ml and 250ml

Copepods are a type of tiny crustacean zooplankton that is considered as the world’s largest bio-resource. Most aquatic species are dependent of copepods during parts of or their whole life cycle. They are eaten by fishes, larval fishes, corals, jellyfish, shrimps, filter feeders and many more.

Suitable for saltwater and freshwater fish, corals, invertebrates and crustaceans. When used as a supplement feed, Ocean Prime will play a vital role in the coloration, growth and survivability.  Available in 50gr pouches, Copepods size: 500-700 micron and 2mm. Click here for more info


Aqua-Crobes is a biological product of natural occurring bacteria and enzymes that reduce the threat to fish caused by pathogenic bacteria. Aqua-Crobes is a competitive excluder of pathogenic microbial diseases such as Vibrio, Pseudomonas, Aeromonas, Streptococcus, Allococcus, Myxobacterium, Columnaris and other gram negative bacteria. The way it works is by creating competition with negative bacteria by introducing bacteria to the water that is beneficial to the fish that live in it. This is a process known as competitive exclusion.  Aqua-Crobes competes with these pathogenic bacteria for the nutrients in the water that they depend on for their survival while waiting to attack your fish. At the same time little peptides are produced that are toxic to finfish and shellfish pathogens. Click here for more info


Reefpearls 5-200 micron contain microencapsulated particles which are stable for 4-24 hours in the watercolumn and have a low leakage of nutrients, thus floating around for a long time and allowing a long feeding time for your animals. Reefpearls consists of a mixture of different pellet sizes, ranging from 5-200 µm (microns), that is mimicking the natural sizes of plankton. They can simply be dosed by using a automated fish feeder.

Reefpearls contain the essential levels of phosphates, however, in contrast to most other feeds, these phosphates are in an organic form (attached to proteins and DNA) instead of inorganic phosphates (PO4) . This will result in lower pollution of your tank and better uptake of this essential element by your corals and other filterfeeders. Available in 5-200µm and 500-1000µm pellet size.

DVH Filtersocks

Filter socks are the most effective and convenient form of mechanical filtration. They remove excess food, detritus, organic waste, dust, and other particulates. Removing these particulates from the water column will reduce the amount of organic matter that produces ammonia and other undesirable substances in the aquarium. Filter socks also help prevent larger objects, such as sand, crabs, snails, etc. from damaging pump motors.
